  Opps, I hit send while still editing.  Append the following to the bottom of
  the text below.
  
  The leading edge votex changes shape/direction with the wing planform.  At
  the tip the vortex it is bent rearwards (perpendicular to the tip edge -
  just like it is perpendicular to the leading edge along the wing spanwise.
  Wake vorticies are an additional / continued manifestation of that vortex
  action/flow.

"""
  As AOA and/or airspeed is increased this spanwise horizontal votex becomes
  more energized - i.e. more lift.  When the AOA gets too large the votex is
  spoiled and the lift effect is reduced/gone (i.e stalled)
